Could my order please be removed. Still getting PMs 

Indeed, they don't have an escrow service. That's the scam.

"Q" entered that blue escrow text into the description field of the invoice. Nothing on the website was altered.

Sorry, not sure I follow. What would reporting that link to Bitmerch do?

What happened:
Yesterday, I made a post with a buy offer for 10 BTC worth of Mastercoin (see here). Received a PM from "Q" saying they would sell the MSC at my desired price using "Bitmerch escrow". This invoice page was linked. I did some quick looking around to see if Bitmerch had been flagged anywhere as a scam, but wasn't able to find anything.

Those of you looking at the page that was linked are likely face-palming quite hard. I was in a hurry to get the trade done as I had other things to do and only took a quick glance at the blue text, which seemed legitimate. Unfortunately, in my haste I failed to notice that the blue text was a part of the description, not the Bitmerch website. I did notice that the grammar was a little messed up, but in my quick search on Bitmerch it appeared they were Russian or something along those lines, so small errors in grammar didn't ring alarm bells. Silly mistake.

I made payment to the "escrow" address and sent "Q" a PM telling them as much. Never heard from them again.

I have never fallen for a scam on the internet, and I've been a part of quite a few communities rife with scammers. Unfortunately, this slip-up was a costly one. Be diligent.

BTC

Proof of Payment:

Here. I've edited them together chronologically.

Additional Notes:
He has been online several times since this and is still sending PMs, attempting to scam people. (see here)

Yeah DO NOT trade with Q. I'm surprised he is still hanging around trying to scam people after already taking my 10 BTC.

I'll put up a scam report now so people are more aware. e: done

Just a heads up on this: he does indeed appear to have done a runner.

Communication was quick, then I deposited the money. Communication stopped, though he has been online several times since. A harsh, 10 BTC lesson learned.

Due your due diligence people. You are not immune.

If you are correct, I believe I may be too late.

Looking to buy 100MSC @ 0.10 (10BTC total)

Thanks.

So, I wonder if we're going to clear the $250 mark this time. Last time we got there, Gox crashed horrifically and that seemed to have a pretty dramatic effect on the value. The load is spread much more evenly across exchanges now, so I imagine that will be much less likely.

Interesting times ahead, indeed.
